What must I do? the lawyer asks

It's not a bad question really.  It focuses the conversation and spells out the way forward. 
What must I do, Lord?

Now, as long as you are not substituting your work (you know, those good deeds which you convince yourself will make you acceptable in the sight of God) for the work of Jesus (who makes us acceptable on the cross, by forgiving and redeeming each and every one of us) then it is, in fact, a very good question.

Because God is meant to be practiced; not just talked about, but practiced.  Your core values are crystal clear in the deeds of your day to day life.  Jesus calls us to align our core values with God (to give life, to bring life to others, to forgive) - and then act out those core values every day.  To do God.

Like when you see a man beaten and robbed and left on the side of the road to die, and you choose to stop, bind him up and arrange for his care.   The lawyer who prompted this telling of the Good Samaritan parable started it all with the question, "What must I do to inherit eternal life?"  In the end, even the lawyer recognizes that the Samaritan, the one who did mercy was most closely aligned to God's purposes.

Go and do likewise.                                                                                        Luke10.25-37
